Sorry for my english is not my native, german is my better language when You understand, i could write it in german.
Important is to say, the two new digits 7 and 0 added there on bayonet sn are of same high and font as scabbard ones,(different to typical visible on bayonet) so it was reserialed after the scabbard was done, which i assume scabbard was newer made and completed with a reserialed older bayonet 9194, from this i assume the b letter was added later by reserialing, from this 9194 must be from range without letter or a but a letter is no visible there. b.r.Andy
